A few questions on a reliable engine rebuild for a 70cc kit

Now i have my runner 50 im looking to buy a 70's kit, exhaust etc. But before i do that im thinking of changing the crank, bearings and so on as i think i've read its better for an engine rebuild when tuning?

ATM on the runner i've got a ZX on and thats it
What crank would you suggest? (I'm thinking about an MHR Rep or malossi sport) but i read someones post saying you have to use certain type of oil, petrol etc? dont know if its true could some one say? also bearings? and C4 mains or whatever? where could i get these? and have i got the right names?

lol sorry for all the complete newb questions but basically i want to 70 my runner without it going pop the next day.

Thanks in advance.

 

Theres me thinking this forum is here to help :msn1:

#1 patience


#2 oil, you are best to use a good fully synthetic no matter what (usually about £6-10 a litre.) the crank it's self dosnt need different oil but you start to throw more power through a set of bearings (mains, big-end, little end etc...) then you start to need somthing a little better to lubricate it.

malossi cranks in my opinion are overpriced although they are pretty bulletproof by all accounts.

c4 mains arent really a necessity but imo they make the bike smoother and in theory last better with more powerful bikes (they have closer machining tolerances than standard C3s)

 

blahhh

I'm thinking of just throwing a MHR Rep in there for now, then start saving. Will it work fine with the ZX i have?

 

You go do that....

You know what the real answer is in your original posting and now your just being abstruse and satrical. And if you vocabulary doesn't stretch to this comprehension, I suggest you research it, (thats spelt G-O-O-G-L-E :tup: )

 

I know what the answer is in my original post? do i?

and how am i being abstruse?

As for 'satrical' I believe you mean satirical? so i suggest you do a bit of research mate

 

Here's a tip for free; tread carefully...

You previously said

"But before I do that I'm thinking of changing the crank, bearings and so on as I think I've read it's better for an engine rebuild when tuning? "

and then you say and ask:


"I'm thinking of just throwing a MHR Rep in there for now, then start saving. Will it work fine with the ZX I have?"

Very contrasting, but hey what do I know? As for abstruse, well the above is very hard to understand my "school boy" friend

 

He doesnt need to he knows exactly what to do...i answered all these questions for him a couple of days ago in a P.M...

But obviously he doesnt trust me or thinks that you lot are going to say something different...but you wont...where do you think i got the info from

 

The Leo Vince ZX is a 50cc pipe, so it will most likely restrict a MHR rep.
