Re: Do KR1S wheels fit In KR1 ?

no need to change the yolk. Yes, they are different, but not in size.

Re: not rev'ing past7500

max regulator output depends on one thing : the battery. A 12V battery "in rest" is empty when it only has 12V, so it needs a lot more to charge up again. A lead-acid battery cell is charged when a cell has 2.1V . in a 12V battery, there are 6 cells so a 12V battery is charged when it has 12.6V in r...

Re: not rev'ing past7500

Noo den mouser! I have some info that may help. Not guaranteed though! When I first got my kr1s, then my electrician friend came round to solve some problems on it. One of the screw ups he found was the stator and pickup wiring was butchered. Thier are three wires from the pickup, and one or two go...

Re: not rev'ing past7500

However does it not operate the powervalve motor ? it doesn't when switching on the contact. but the electric charging system always makes enough current to ride and use everything on the bike and extra to charge the battery. maybe if the battery is too dead drawing away too much current, what Mart...

Re: First Impressions

can only compare with the RGV (22) on a track : frame/suspension, the RGV is better, allthough the RGV does a stoppie much easier while it didn't feel like it braked harder, don't know why. I prefer the KR engine , has more character and gives a bigger kick in the but when the pipe starts to work. f...

Re: not rev'ing past7500

I've never had an even remotly decent battery in my bike. There is always one in, just to swallow the excess of current made by the charging system. My battery is so dead the bike won't start with the lights on as they (lights and battery together) drain too much power from the ignition while kickin...

Re: not rev'ing past7500

a strobe is used to check the timing of the ignition. if the strobe flashes, the plug emits a spark, so if you strap the strobe on the bike and it still flashes at 7.500 rpm, you know at least that your ignition is still working. KIPS not opening can never be a reason why the engine wouldn't rev pas...

Re: not rev'ing past7500

Re: Trackday preparation

front 2.3 bar, rear 2.2 bar, that's what I always use, with any bike, track or street (but I only ride for fun, so my street-pace isn't much slower).

Re: Shrinking a 300 to a 250

I'd be interested in the 300 kit for racing A KR is already oversquare. going even bigger on the bore means you will have even less time-area to fill the cylinder. in cc, the increase of the bore is squared (Pi*D^2) ; but on your port-real-esate-side, the bore increase is only single (Pi*D) -> the ...
