vintage race CB350 - last 10% is the hardest

[teazer]

How is the bike - made much progress and what plans for the coming Off season for the bike? Did it ever find its way onto a dyno?

Sorry nothing significant to update. Had a lot of life changes that pushed the motorcycle onto the back burner for a while. Bought a new house, rented the old house, renovated the new house, wife got new job, wife got pregnant, I got a promotion at work. Busy busy busy. I've got a new Barnett kevlar racing clutch to install, lots of drilling and safety wiring, fork service and some steering and footpeg tweaks to resolve. None of them are particularly hard but I didn't want to tear the bike apart until my garage was situated and I could afford to take my time with a partially dissembled machine. Garage is almost there.....

Nothing new to report on this bike. Dusting it off, moving it outside and taking a few pictures is the most work I've done to it in the past 12 months. But I'm looking forward to chipping away at it over winter a few hours at a time to get it over the hump. It looks complete but still needs a lot of development and fine tuning. Race bikes always seem to be works in progress. I plan to sticker the bike up but haven't settled on the exact livery yet. It will get white number plates, black numbers, and probably just some large Todd Henning Racing THR decals. The tank will stay bare polished aluminum. The belly pan will get painted black (it's already black gel coat) and then covered in gold reflective foil. The bike needs a fork oil change, foot peg plates bent outwards for clearance, suspension sag and preload setup, new Kevlar clutch plates installed, oil vapor catch can, seat foam, steering damper install and lots of safety wiring.

hey if you be racing it you may be interested in the cb450 clutch basket mod 10% higher(lower numerically) primary drive ratio with the setup ,there are a few good solid reasons to do it and the bonus is it is a very easy swap and still uses 350 clutch discs and innerds
i have done it to my 350 already

What are the dimensions of your 2-1 exhaust. I've developed one for the CB350 but I'm still working on tuning the midrange using Mikuni VM30 carbs. What jets are you using as your pipe seems to take throttle well

I'm using a 2-1 system with 22" x1.5" headers leading into a merge collector that is 4.75" long and 1.7" diameter at exit, then 13" midpipe @1.7" then bumps up to 1.9" tailpipe running 12 inches then into a 16" megaphone muffler with a straight through 2.0" core.

Excellent build quality. I have a few questions if you would be so kind to talk about them. You mentioned you are using the same conti attack 100 90 18 tires on 2.15 rims, front tires or rear your using? Do you think the front 100/90 would fit a stock cb350 fender?

Also where did you get the gold chain adjusters?

However the exhaust holding up? Does Chris f still make the exhaust systems? I would like to buy one.
