On board footage

Don't get all excited thinking you'll see the next Reed/Hailwood battle. It's a couple of geezers farting around learning the track. Shot in August on my Pacific Northwest racing/road-trip. Full report soon.

MK 1 shininess

My friend Chris has finally received his bodywork and frame back. His MK 1 is shown earlier in the blog. This is going to turn out nice!!

DTF's

Finally got around to fitting my DTF head guards. I'm all set for Seattle Vintage Days now and will post again soon.

July update

I raced in Portland in July at the Vintage Days put on by the local organization OMRRA. Much to my shame I didn't take pictures as I had a new on board camera to try but unfortunately I was having technical difficulties with it.

Quick report. The Guzzi ran great. I installed a new gear set 8/35 as the 7/33 I used at the previous race was too short for Portland's long front straight. I was topping out at 8,000 rpm well before the end of the straight. The 8/35 made a huge difference. I have a wonderful gearing chart from Guzzitech.dk. Click here for the link. Scroll down to table of contents and the gearing Excel spreadsheet application will be there. Using the chart I was able to calculate that with the 7/33 and tyre combo I was doing 135mph at 8,000rpm. Using the 8/35 I would be at 142mph. In the race I was hitting about 7700rpm at the end of the straight. Not necessarily any faster but it meant I wasn't flogging the engine unnecessarily. My shift points remained the same so acceleration didn't suffer. Thank you Charley Cole of Zydeco Racing for the 2 week turnaround time on the gear set.

I have finally found a jetting combo that works too. In the past I was way too lean and I think this may have been the cause of my failed rod bearings due to pre-ignition....

Without my usual long-windedness here's my jetting at the moment: 41mm Dellortos. 165 mains, 265 needle jet, 2nd clip position. K4 needle. VP110 red race gas. 30 degrees of timing.

I think there's some tweaking to be done with timing, plugs etc but I'm definitely in the ball park. The Guzzi is pretty quick (for an old tractor).

Had 3 races. Got a second and 2 thirds. Battled with a Honda 750 the whole weekend. He beat me twice (:

Steve Arnett's Duc was still broken but we will be racing this coming weekend in Seattle, his home track. I've been prepping the bike to make it somewhat eligible for the Seattle Vintage Days. Technically they have a 750cc, 1972 cut off year but the Guzzi kind of looks the part. Nobody really cares and are just happy to have bikes on the grid. I did have to take off the lovely Astralites and source some Borrani wheels to make the bike more 'period correct'.

Seattle 'tweaks': Borrani wheels with new Avon Vintage race rubber for skinny rims, jetting, fork brace to handle the crazy downhill full braking hairpin. See a vintage bike go around Pacific Raceways here .

Hopefully I'll have some footage up too in a couple of weeks.

Below is the bike almost ready for Seattle.

Dave Shaw of Finebau Forge Custom Products sent me some great headguards for the racebike. While designed for the newer line of Guzzis they fit my Sport 1100 engine just fine. The beauty of the guards is that they attach under the valve cover and are fixed by all the valve cover bolts. In the event of a crash they will protect the spark plugs and head fins without breaking off.

I hope I never have to write a review of their performance but you can see some crash test shots in this small product promo video that prove they do the job they are designed for.

Portland pictures

This is not what it looks like. It was actually a short cut.

My friends Mike and Rob flew up to see the races (that's their story, I'm convinced the famous Portland beer had more to do with it) and actually had steady hands for a few minutes and took some very nice shots (in more ways than one). Click on the following link: here to see the art shots.

Racing recap

It's been a month since I had 2 weekends of racing in a row so I think it's about time I catch up on the blog.

First up was the AHRMA event at Willow Springs located here in Southern California. Generally I'm scrambling to get everything ready but this year I was fairly relaxed and just had a few things to get ready.

The Wednesday night before Friday practice I decided to check the timing on my Honda 160 racer. I had changed the clip ons a few weeks before after crashing the bike at a trackday but hadn't actually run it. I wheeled the bike out to the car park of my workshop and proceeded to bumpstart it. Usually it starts right up but this time it was being uncooperative so I dismounted and ran alongside while pushing. Big mistake. It fired right up and immediately went to full throttle, tore out of my hands and went careening into the side of my workshop. DOH!!!

After picking myself up of the ground I killed the motor and surveyed the damage. I quickly went from thinking the bike was completely destroyed to realizing that perhaps it was salvageable.

Luckily the left fork had taken the brunt of the impact and saved the engine. The forks were bent,the fairing was broken, the top triple clamp was broken and the bottom triple was bent. It also slightly bent the wheel. Damage to me was scraped leg and torn shoulder that is still giving me grief.

I had spare forks and triples so they were replaced within an hour. The wheel would have to be taken to Buchannans Spoke and Wheel the next day for straightening. My friend Ralph was kind enough to let me come over and use his facilities to fix the fairing. I also needed to mould a belly pan in fibreglass from my old aluminum one for the Guzzi so it ended up being a late night........ Ralph was busy sorting out his Honda 160 engine that he had secretly milled special pistons for. The truth only came out at midnight when he started the engine and the pistons were kissing the valves. He's a sneaky one that Ralph!! He got it fixed though and it's a flyer.

Thursday was spent running around picking up last minute stuff, finishing up work and generally feeling tired and stressed. The 160 came together but it still had a sticking throttle which I would just have to deal with at the track which is something I hate doing as I like to have everything ready before I go. I finally got both bikes loaded and ready to go at 3 a.m. Friday the day of practice.

I'm reaching my 1 finger typing limit so I'll keep the rest short:

Ralph fixed the Honda throttle. I took 4 2nd places on the Honda. Video here.

The Guzzi was handling crappy. It blew an oil pressure gauge line covering the bike in oil. I was my usual useless self at Willow. Steve Arnett and his Ducati were blazing fast. I didn't take any pictures.........

Next up Portland:

1 week later: Somewhere on the 5 freeway.

Returned from Willow Springs on Sunday night. Caught up with work and life, prepped the bikes and headed to Portland on Wednesday evening.

Kristina and I stayed with our friends Dave and Ann Stark near San Francisco that night. They are both 160 racers too and we were all going to convoy up to Portland the next day. Dave is the announcer at the west coast AHRMA events so we had a running commentary the whole way up via Dave's walkie talkies. Nothing like recreating scenes from Convoy to keep you occupied for a 600 mile trip.

The Portland event was the first time AHRMA had visited and so a big effort was made to make it special. There were 55 entries for the Le Mans start 160 race. Ralph flew up, Steve Arnett drove down from Seattle and pretty much the whole west coast racing contingent was in attendance.

Racing: The Honda ran great. I took 4th in Saturday's 160 race. Video here: 160 race. More.

The Guzzi was giving me problems. During Friday and Saturday performance felt flat. At full throttle it would run better letting off the throttle so I was under the impression that it was jetted too rich. I was already jetted lean with 128 mains so I was a bit perplexed. Being busy with the the Honda and lazy by nature I was unable to focus on the problem. On Sunday I finally got round to putting 140 mains in which made a huge improvement. The bike was pulling better and I'd shift into 5th about 100ft earlier. It felt great to get it sorted. I have changed the exhaust from last year for a freer flowing set so I think it breathes better hence the need for richer jetting.

Also discovered that 1 or more of the front brake discs is warped. Braking into turn 1 at 130mph to be met by major juddering is not fun and as a result my lap times were a little disappointing. About 2 seconds slower than last year.
