Glenyboy Posted May 4, 2011 Report Share Posted May 4, 2011 Bit of a strange one here!! I need to make my banshee run at 19-20hp, not permanently just for a power run on a dyno. Reason being is that to make it road legal over here in the uk it has to have proof that it runs at this power or under. Can adjusting the screw on the throttle do this or will it still peak out high? Quote Link to comment Share on other sites More sharing options...
dirtydownunder Posted May 4, 2011 Report Share Posted May 4, 2011 bigger cc domes and retard the timing a bit (not too far or it will get hot), taller gearing , stock pipes, restricted mufflers and or carbs. spk to the dyno operator and ask him to play with the corrections, to read a lower hp.

Glenyboy Posted May 4, 2011 Author Report Share Posted May 4, 2011 Sorry I forgot to mention I'll be running the bike stock, everything has to have kite marks stamped on it, like reg numbers on the pipes and lights etc. Plus I don't have an aftermarket head so I couldn't change domes, also would retarding the timing make that much of a difference?

dirtydownunder Posted May 4, 2011 Report Share Posted May 4, 2011 run a thicker head gasket, and restrict the shit out of the pipes n carbs. retarded timing will help some what but prolly not worth it. seems like alot of effort ?, you going to swap parts around when you get home after licensing ?

Glenyboy Posted May 4, 2011 Author Report Share Posted May 4, 2011 (edited) I only really need a printout showing a peak of 19-20hp to tell the truth obviously with the banshees rev range because they ask what it revs out at. The test itself just checks that it's in good order and to make sure it's not dodgy. I may just have to have a word with the dyno people and see if they can make me dodgy power graph of some sort. Whenever I've asked people over here who have done it they say just to adjust the screw on the throttle. Oh and I've got a set of t5's waiting to go on it once it's been passed, I'll probably fit some pods and advance the timing, looking into reeds aswell just not too sure whether to get the ones with or without the cages? Do they make that much of a difference? Edited May 4, 2011 by Glenyboy Quote Link to comment Share on other sites More sharing options...
dirtydownunder Posted May 4, 2011 Report Share Posted May 4, 2011 id be talking to people over there, that have licensed their banshee's. youl be fine with stock cages and after market reeds, you can port your stock cages if you like to do stuff. some sponsors on here like "chariot" have after market cages that are pretty nice.

Larry's Shee Posted May 4, 2011 Report Share Posted May 4, 2011 FULL REVERSE Rig restrictors in carb, flat rubber washer with about 20mm center, jet rich, maybe retard timing bit . Pay dyno operator off for the last few HP Quote Link to comment Share on other sites More sharing options...
tedd1 Posted May 4, 2011 Report Share Posted May 4, 2011 Adjust throttle to open only half way. There is a stop screw on the back of the thumb housing. Quote Link to comment Share on other sites More sharing options...

Glenyboy Posted May 4, 2011 Author Report Share Posted May 4, 2011 That was my original plan just wasn't too sure if it would spike above 19, as it'll be stock I probably won't have to worry Quote Link to comment Share on other sites More sharing options...
