Honda Spree and Elite 50 Forums

At 52 I felt it was running out of legs, another 6 mph may have been possible but Id like to know how and what I need to do to it. Veedub has quite a bit of experience with these engines for certain. Just gotta catch him while hes around for the full story.

Just got my 01 elite sr back from graphite9 who by the way is a great guy to work with. Had him install
Naraku sport variator
Polini 6.9g rollers
9:44 final drive gears.
Prior to this my SR barely wanted to do 32 on flats and felt lacking all around. Now at half throttle on flat it pulls 35 and will peg out fast at full throttle. Hit 48 on a marginal down hill and cut the throttle back because of traffic.

Im in town for 2 days and during the ride yesterday it started raining. When pulling into the drive she started to bog out so hopefully its from the rain, if not hopefully it was the cylinder ha.

I swapped out my stock gears for 9:1...I didn't notice any difference (loss) in the take off over stock. Only the top end was soooo much better.

Over looking Denver on 84th ave and federal. She does great in the thin air.

My 99 purple is way faster than my 01, Im going to go ahead and build another af16e and swap it out with the 99 and put all the 99s stuff on the 01 and see if I get the same results. Ive had quite a few elites and seriously my 99 seems like its the one the factory put some extra love into when assembling or its the fact it was owned by a farmer who only cruised around his farm dirt roads for the first 486 miles. It was a really good break in I think.

That is good news, I just ordered a set of 9:1s myself for a basically stock '97 Elite S. I too was a bit concerned that it would be too much for 50cc.

I swapped 9:1s on my 186 miles 01 and its a real dog now. If I can make it to 35 before a big hill it will maintain it, if I'm going uphill from a stop I'm going to have some angry cagers behind me. Downhill it's sweet. With stock gears it pulls the front wheel, 9s it pulls a lot of strain on my engine and cvt. Currently the 01 has a malossi cdi, hrc variator and ramp, malossi belt, malossi white center spring, malossi wing bell and a prodigy clutch. Stock cylinder, jet, air filter, air box(tab cut), and exhaust. Top speed is around 53 downhill. 35-38 on flats. Needs more power.

With 45 miles on the odometer, Flash 3 did 49 - OK, Downwind... - with stock everything but belt cavity contents and 9:1s. Acceleration wasn't a problem except for 0 to 10, nor were hills. Maybe yours is down on power, but I can't think why with 186 miles. I was using 7g weights, if I remember correctly, but all else including airbox was untouched for a week or 2. The higher revs yielded from the light variator load (stock rollers were 9s) compensated for the taller legs, again except for 0-10. Is it possible the Malossi CDI timing curve is too aggressive for the stock mill?

Hi LMH.
try some lower weight rollers like 7grams. check the belt make sure that seats all the way up on the rear clutch. you need a little bit more miles on the belt to seat correctly, and motor is still on its break in period. The more miles the faster.

It's using 7gs, belt is a malossi, funny enough 0-10 isn't the problem it's after. The 25-35 takes forever, then 35 on is impossible some times. I feel it needs a bit more power the trans does all it can it seems. It's physically hotter also after a ride than usual. Seems like its just working too hard.
The malossi cdi works wonders on any displacement or port design as I use it on my completely stock 49cc kymco hitting 55 and the 99 purple 50mph that's in this thread. Ill try the polini cf reeds and 87.5 jet when I get more time.

Hi LMH. sounds like the Contra spring.
do you know what RPM IS on the rear center spring?
The malossi cdi has a very high rev limited that's why your getting more speed on the other scooters.

No rev limit on any cdi in the us or any aftermarket for what it's worth ha. The higher rpms is from a better curve with more advance. It's a nice upgrade.

Hi LMH.
If your motor revs up initially and then the rpms drop as you excel, you need a heavier torque spring.

Too high of a rpm spring on a stock cylinder will limit your top speed. It never loses its engine speed, it just doesn't have the bite to match the bark. I'm running the malossi white currently in that engine and the white is a heavy as a stock cylinder can handle with out losing too much top speed. I run the yellows on my stock geared bikes flawlessly.
When I get time it'll get more power with a couple bolt ons. Gotta love 2 strokes, change the pipe and change the power band.

Greetings:

If it's hot, is it because it's revving too high? My first inclination apparently was incorrect in that case. The stronger center spring may simply need heavier-than-7s rollers to match its tension?
