Thruxtonboy

Hi Guys,

I'm from Holland and last year (2007) I bought myself a new Thruxton (carbs version). Sinds I started to ride this bike, I was missing some power, especially in the higer revs. Before the Thrux I owned a Daytona 1200 and there was never a leake of performance. But, I really love the Thrux, the looks, the style, the sound, the way the bike rides, almost everything. The only thing missing was a surtain final shot of power. After 5.000 revs the speed was gone. So, I decided to do something about this and now I'm involved in a heavenly tuningjob. The whole thing started wenn I bought myself a set of Hot Cams from Thunderbike (NZ). After receiving these things we wanted to build them in the bikes engine. But, because we have to take the cilnderhead of, it seems to be a good idea to do a little porting and flowingjob on the cilinderhead. Then we found out that the stock compression on the bike was very low (9,2:1) and to improve that we also bought the 904 cc Wiseco kit. This must bring a CR of 10.5:1. The stock CVK carbs has to leave also, in stead of them we toke de Keihin FCR 39's. Taking the cilinderhead of we also noticed that the stock valves are quitte small, especially the exhaust valves. For that reason we get ourselfs bigger valves.
The last things I bought was a Barnett clutch and a PRETECH 6 pot caliper. I also get me Wilbers racing suspension (Germany) and a NH steering damper.
We expect the bike to be realy, realy fast en strong after ereything is done. The guy who is doing all the tuning on the engine is a very (VERY) experienced tuner of racingbike engines here in Holland and he expects that the Thruxton will go over 9.000 rpm. Because of that we also have to replace the valvesprings for stronger ones. I will keep you informed about my project, wenn I now how to do it, I will also put some pictures off my project on this forum.

Welcome Thruxboy! I agree what a greeting. You're doing mods way beyond my wrenching ability and wallet capacity. Can't wait to see some pics. She should be a rocket that's for sure. Enjoy our on-line club and don't be a stranger.

Nice motor set-up your working on! Be very interesting to see what your opinion of the Thunderbike cams are - I've been on the fence for over a year on weather or not to try anything other than the stock cams. I've the bigger intake and exhaust valves, forged HComp pistons, ported, Speed triple valve springs and 42mm HSR flatslides. What do the advantages seem to be with the Thunderbike cams - more lift?? duration??
Their charts seem to indicate large gains at higher RPM - which is fine with me - I generally keep it in the 5000 to rev limiter range when having fun anyway. Keep us posted.

Nice indeedie! Did you coat your valves, or is that just the camera casting the colors? Also, is there anyway you can post the cam lift, intake and exhaust opening and closing events? Thunderbike has be tight lipped on thier cam specs. It seems you may have exactly what some of us have been looking for
