as i want to run mine long stroke, sip do a longstroke version, so that you don't have to put in a packing plate or spacer, its in anodised red, for the sake of 100 quid i would rather buy that off the shelf than faf around getting one machined.LI150 wrote:I tried first without a fuel pump but when tank got low I had fuel starvation. I would say try without first and see how you go.MCH wrote:is there a way around not having a fuel pump fitted? or is it a necessity?
are the sip heads better ?
im wanting to stay with the cosa clutch and elecy start,
is it also worth getting a different ignition system?
I have tryed the Malossi Head - Compression is high pinking occured
Next I tryed the MMW Head - Didnt seem like I was getting the most out of the performance
Next tryed the SIP Head - The best quality bit of kit I ever bought for my Vespa. A tadge expensive but well worrh the money IMO
Nothing wrong with the Cosa I didnt use the one I had as I wanted to change the gearing and got hold of a 7 spring 22 tooth clutch so used that. Also I like my elecy start so kept it.
No keep the ignition you have, I just fitted a MTECH advance retard system to clean up lower revs and aid with cooling at higher by running a more retarded timing.
Hope this helps.. :bouncyeng:
also talking about the gearing, as im running an oversized tyre on the rear, what gearing do you suggest i try?
also how much do you reckon in labour would it cost to port the casings and then set it all up?
once i have everything I think I will take it to diablo moto, even though hes best with polini kits, i know if i take it there i will get the best service
