proma GP or Boss?

which is better for low end? I looked at the wiki, and it is really less than helpfulas far as actual performance. Any input from ownrs of both? I'll be putting it on a 65cc MK with a 15mm bing.

GP

Re: proma GP or Boss?

for low end?...Gp

in general...BOSS

Re: proma GP or Boss?

why "in general" does the gp limit top speed?

Re: proma GP or Boss?

not much but the metra 65 isn't the greatest low end kit, so go gp!! I think its a great match with the metra!!

Re: proma GP or Boss?

proma for low end, boss for upper mid range

Re: proma GP or Boss?

ok, my other bike is a 50cc stock. boss or Gp on that one?

Re: proma GP or Boss?

biturbo

Re: proma GP or Boss?

lol only if u have to cut it to :P

Re: proma GP or Boss?

gp is nice all around, boss is good for top, never buy a biturbo and

"not much but the metra 65 isn’t the greatest low end kit" wrong. it is a very low end kit, the lowest i have come across.

Re: proma GP or Boss?

so the boss would be better on the metrakit since that kit has it's own low end power and the gp on the stock to help boost the low end to get my fat ass moving. Thanks guys!

Re: proma GP or Boss?

fred david is talking about a 65metra with a phbg carb however with a bing they have bad lowend COMPARED to a polini, compared to a tccd they have good lowend.

buy both pipes lol
