Sean Posted March 5, 2010 Report Posted March 5, 2010 Hi guys took some time out over the Christmas break to rebuild the motor and give it a quick freshen up. Started as a top end rebuild, and went on the have the crank cases matched to my Mick Abbey barrel, re sprayed them in PJ1 satin black, all new bearings, a nice NOS crank a got for £32 a few months back, made a 10mm reed valve spacer on the milling machine at college, machined the fly wheel lighter. Heads been skimmed and re profiled and it now running at 0.8mm squish and a tz style o-ring, so no head gasket . Got some nice boyson duel stage reed petals aswell. Made a little powervalve cover out of some Perspex I had laying round. Back in the bike now just getting some run in miles down before giving her a thrashing this summer. Seems to pull amazingly well at the minute and haven’t wound her up yet at all, cant wait.
Devon Posted March 9, 2010 Report Posted March 9, 2010 stupid question I know but what were you doing with the parts in the oven?
Sean Posted March 16, 2010 Author Report Posted March 16, 2010 Baking the PJ1 paint on of corse might just be me, but by doing this seems to make it alot stronger, my carb bowl leaked over night and i simply wiped the puddle of full off the crank cases. not a mark or blemish. Cheers Guys
Sean Posted March 21, 2010 Author Report Posted March 21, 2010 Did indeed, Putting out 17.5 at the rear wheel so loads more work needed lol
monty_zac Posted March 21, 2010 Report Posted March 21, 2010 Is that restricted? I thought they were in the high 20s in full power?
monty_zac Posted March 21, 2010 Report Posted March 21, 2010 Just to add, great job you have done in restoring this TZR, I never would have had the focus at your age!
Sean Posted March 21, 2010 Author Report Posted March 21, 2010 Still running a standard exhaust on there, and the italian import versions had far more power nearly 25-26. Cheers for the positive comments guys
