MOPED ARMY

If aftermarket 3 shoe clutch throw it away and get/use stock puch oem 2 shoe or if you're lucky OEM three shoe clutch. you could tell OEM clutch for that it has a date code on it.

Get a real puch clutch put stiff kickstart Springs in it not blue.

With a 65cc kit performance pipe and filter you should never have to gear lower then 17x45 (add power add gear) you should set timing and jetting correctly to go 40-45 with great take off and good hill climbing.

If you only go 25-30mph (which is slower then stock) with a kitted bike then I'd quit and buy a scooter for you're so out of tune it's not funny

You know roff, just because you're almost always right about puch stuff doesn't make insulting guys with a single post to their name like... Okay.

Yeah, answering the same questions over and over can be obnoxious, but that's why REAL forums have like, stickyable threads and categories for "New member? Look HERE first" collections of threads, posts, etc.

Part of why MA sucks is that nothing is ever tagged and nothing is ever sorted. The search function is finnecky at best and even if we say "Go read all Ken Roff's Stuff", it's not well organized.

Hi, thanks for all the replies.

Some more details: I have an Airsail 65cc kit (from the puchshop.de, I am in the uk), 15mm carb with no78 jet, techno boss exhaust. Am I in the right ball park in terms of jet size?

I have read Ken's article on timing and have it set up at 17mm btdc, had to dremmell the slots as suggested. I've checked with timing light and I'm spot on here.

The clutch is original, as fitted, 3 shoes and they look like they have plenty of meat on them. All I've done is change the springs to blue. I have bought a reinforcement plate but not yet fitted. Don't think I'm quite there yet.

I've had a look at all the articles on clutch tuning including the chart that's kicking about.

Apologise if I'm asking the same questions as previous posters. As I said I'm pretty new to these mopeds! Feel like I'm going round in circles changing too many variables at one and need a bit of help dialling into a ballpark set up for this bike.

To be fair I don't know exactly where I am with speed as I have no speedo fitted but speed feels good on the flat, can keep up with traffic around town, just hills I'm having problems with.

Thanks again, guys, any help is appreciated.

78 jet is way too rich...

as far as the clutch tuning yeah, you just have to play with it...took me forever but ended up with a 2 shoe clutch with the kick start springs turned all the way in and then backed out 3 1/2 turns...

when I tried to tune by using the fish scale method I think I was way above 25 lbs...or something like that...

if I tuned it with light spring tension it would just bog off the line...

nice bike btw...

I have the same kit and carb, rebuilt, case matched with a bi-turbo. Metal mesh filter. 78 jet . 3 turns in from flush kick start springs two shoe. Great take off, 46 -48 mph. 17/40 gearing.

i have 14x45 on my magnum and i am very pleased with it. check for air leaks if you are low on torque with that set-up the 64 puts out pretty decent mid range. Your clutch with that gearing and set-up should be locking up at about 20-25 for optimal performance. right around 5500-6000 rpms, which is about 25 lbs with the snordley method.

Hey Mat, questions for you. I'm getting the blue springs for my e50 and was wondering, do you need to remvoe the clutch to install them? OR can I back out the screws, drop them in and then adjust the screws?

If I have to remove the clutch, I see there is a clutch puller but no installer out there. So how would you re-install the clutch after removal?
