EXUP Worldwide

Hey Chris, thanks heaps for the info.<br> it might be time to build a hybrid.<br>thanks again <p></p><i></i>

hi everyone.... i was wondering if the heads, barrels, pistons, are compatable with each other on the above engines....cheers...<!--EZCODE EMOTICON START :evil --><img src=http://www.ezboard.com/images/emoticons/devil.gif ALT=":evil"><!--EZCODE EMOTICON END--> <p></p><i></i>

We solved this by interupting the common color low tension wire to the ignition coil, with a length of twin core wire connected to a male-female style quick click two pin plug, clamped to the h/bar. When the plug is disconnected, the low tension circuit is opened - this may not be the best way and i...

Circus,<br>Thanks for the reply. Its obviously not as simple as big/small = top end/torque etc. Its just as obvious I need to find myself a bookstore and get "educated"<br>Once again, thanks for the help<br> <p></p><i></i>

Has anyone tried a 4-1 or 4-2-1 system using smaller or larger diameter tubing. The theory I've been told is smaller dia. tubing = more torque. Larger dia tube = more top end. My engine will not support an exup system - Any ideas? I've seen a simular idea in practice on a stock RF9what-ever where th...

Yes, No, Yes, No, & YES<br>Its the off-season here, so time to go make some power!<br>Safe riding<br>C.U.<br><!--EZCODE EMOTICON START :evil --><img src=http://www.ezboard.com/images/emoticons/devil.gif ALT=":evil"><!--EZCODE EMOTICON END--> <p></p><i></i>

We ended up taking off around 0.5mm Keep in mind that this engine will not perform on pump gas or aviation fuel without some octane boost type products <p></p><i></i>

My '97 t/ace has had the top of the barrels planned enough to give us approx 14/15:1 comp ratio. It has a very mild port job, altered cam timing, aftermarket 4-1, flat slides & runs on methanol - hence the high comp-ratio. The bike runs well & for the last 3 yrs have had no trouble - hope this helps...
