Engine modding advice.

Right its time for me to go ahead and start with my engine mods. The only thing is I know very little about this. I cant afford to buy everything I need in one go, so what is the best way to go about it? The stuff I have priced up so far is -

Exhaust
Air Filter
Variator Kit
70 kit
Carb Kit
Rear Torque Drive (not sure wtf this even is or if I need one)

If there is other stuff here that I need which I have missed out please correct me. I'm here to learn after all.


p.s its a minerelli horizontal air cooled engine, 50cc.

 

fuck clutch just stronger springs,

go for the bore kit first off all.

 

mhr rep 70 kit yashuni c 16 21 dellorto and spend money on the over bits like jets rollers variator and maybe new bottom end bearings

 

so if I just put the 70 kit in first is there anything else I would need to do or buy to make sure it runs correctly? or does it come with everything I would need?

 

comes with everything you need to make it run.

but will obviously need jetting and rollers to suit.

 

right so if i gota upjet it would probably be worth getting a new air filter while im at it?

Hell I may as well get the new carb while im doing that too....arrghh confusion lol

 

air filters useless tbh , some ppl find they help performance but i dnt rate them , look in the guides someone (minor i think) has written a wicked guide on 50cc tuning , all the info u will eva need is right ther mate

 

unfortunatly I have to change the air filter anyway. The old airbox is right up against the frame and I need to jack the rear end up to get my new wheels on, the old airbox prevents me from doing that.

 

mod it then , standar airbox is better than a open filter , wobbly explained it all here http://scootershack.co.uk/airboxguide.html makes sense to me

 

bollox

cant really mod it at all. The only way forward would be to put a longer hose on the thing and attach it to a totally different part of the bike.

Would that work or is the length of the hose important?

 

get a new crank aswell

 

:beer: :beer: :beer: :beer: :beer:

get this man a beer, someone at last has learnt that adding power in the top puts extra stress on the botom.


i agree, crank should be the FIRST thing you do when modding a motor

 

But the most fiddly thing tbh , i got a quote of 100quid
suppose its better then getting a full rebuild when it all goes bang

 

so is it safe to put a 70 kit in without changing the crank?

 

all depends on what 70 kit.

the engines life and milage.

and if it gets set-up right :bird: imp:

 

the engine is in good shape. The bike is a '92 but was owned from new by a woman who only used it now and again to go to work on and so has only done 3500 miles.

Care to recomend me a 70 kit? Its for a 50cc air-cooled minarelli horizontal.

 

am not too familiar on them engines tbh but a sport kit will be fine.
