Hi. Recently had Morley muscle kit and a full UFO system on my bike and after it come back from the rolling road the clutch is now slipping. I gained 40+bhp so it's obviously struggling to cope now. Would heavy clutch springs solve the problem?

Just got my bike back from tim blakemoore racing. After initially only making a feeble 90hp, two carb diaphrams, a full dragster system and a morleys muscle kit later I have a 135hp monster! I honestly can't believe the difference. It nearly pulled my arms off! It's making more power than my 900...

Hi. What V-boost setting would you recomened with a muscle-kit for most power? I'm having it installed and setup next week and wondered if it needs to be left in the v-boost setting it's setup in; ie 3.5k or 6.5k rpms. Either that or have it on full time. I've a full exhaust system if thats of...

Just a quick one for you: Is it a simple case of a few alan key bolts and lift the head off? Do I have to replace gaskets or anything or take any special measures? Any advice would be great. Thanks

What'll give me the bigest power increase for the least money? Would a nos system blow a stock engine to the moon? At the moment all I have is a 4-2-1 dragster exhaust and soon to be fitted morely muscle jet kit. I made the mistake of riding a gen 2 very briefly and now mine feels slow!

Just installed my ufo dragster system and ditched the cobra's. What can I say; Its like a different bike already. Much more low down grunt and mid-range than before.... and the noise! It sounds like nothing I've ever heard! Only way to describe it is pi##ed off NASCAR noise. Absolutley awsome...

Hi all. I've just ordered my 4-2-1 UFO system to replace my cobras. But before I send it off to be setup I was wondering how to modify the stock box as I'm now pretty skint. Also what's the most cost effective way to match my fuelling to my exhaust? Thanks guys

I've currently got headers and cobra slip ons, with stock jets(I think) and stock filter. I'm thinking about getting either a UFO 4/1 or 4/2 system. I just love the V8 muscle car noise! My question is: Am I likely to see any significant bhp gains over my current set-up? I no cobras alone are...

Hi. Just a quickie. Is it worth ordering a K&N air filter over a stock one? Will there be any more induction noise/ gained hp or is it a waste of money?

Whilst servicing my bike I noticed my rough Idle when hot may be due to one of my front ht plugs arching. It seems to be arching straight through the side of the rubber plug/cap. Is there a cheap and easy solution to this? If I buy new cable can I use the existing plugs/caps and screw...

Hi. I've a full exhaust system on my bike with stock jets. I've been told it would be a good idea to up jet to stage 1 0r 7 What are the pro's and cons of both? Will 7 cost me my v-boost? Is there much real world difference betweeen them or is it just the seam of your pants difference? Any...

Hi. I love the sound/look of my cobra slip ons. However I've been told they're costing me a good 15+ hp due to lack of back pressure. Is it possible to stuff my own baffles?

Hi. I've recently bought a vmax and today was the first time I've really gone any distance. It was fine whilst moving but as soon as I hit heavy traffic it started popping like hell at low revs and wouldn't hold idle. It's rarely been used for the last few years by its previous owner and needs...

Hi. Got cobra slip ons and a stainless manifold on my bike. I've been told by a reliable source that I could be losing upto 20% of stock power or 25hp by having them. Is there any easy/cheap way of getting it back or is it a case of sacrificing looks for performance and selling them and getting...

Hi all! I'm new to the forum and cruiser/muscle bikes. After a couple of years of wondering if 1000cc superbikes (as pictured) are still for me (few/lots of near death experiances!), I got a handsome blokes bike. It's a 99 model with 8000 miles in carbon with cobra slip-ons, stainless...
