Trx pre modern racer dyno result

Post by Curmi. » Mon Jan 12, 2015 11:22 am

Hey guys finally dyno results after all the work. Not a bad result for stock bottom end. For those who haven't seen the mods are, standard bore size, fcr carbs, 2mm intake valves, stock exhaust valves, skimmed head, port and flow, stock cams, projection exhaust. Not a bad result I think. What do you guys Think I would get extra mainly in the midrange, also top end with kent cams. Cheers

That's a healthy curve and nice power.

Similar to the 89bhp I got just sticking on a big bore Renegade pipe/cans and FCR's to a bog stock motor.

Bike looks great too :D

Well done, would be good to see the dyno chart without the rpms cropped off.

Do you have the "before" chart on the same dyno to show the actual gains made?
