I dont know any lambrettas that run plastic head cowlsshamrockexpress wrote:B7es for alot of the small block kits seems good for normal conditions.........
p200e runs b6es.............does anybody run a plug this hot in a lammie just curious to know why it shouldnt be fine in anything stage 4 200 or less.....is there any proof that a vespa would run cooler than a lammie as a rule?????????at the end of the day both simlar compression ratios and fan cooled running simlar revs, i personally have never used a b6es in a lammie but for town riding and commuting it might burn the slightly over rich mixtures better thru the slower traffic!!!!!!!!!!!!!!
any thoughts on this anyone?
I agree, it would be interesting to see results from the various heads available for Lambretta's these days - standard SIL, AF, BGM, GT, Avanti, Reedspeed.Chris in Margate wrote:Now that would be an interesting (not all together scientific ) exercise and it would be good to see any results you've kept.
Yes, a B6 is madness, I know it's in the haynes but you will heat seize unless you are running to and from the shops at less than 30 frankly. Thats the same for a B7 in a lammy. If you are using these plugs to burn off an over rich mixture it's your mixtures wrong and putting in a hotter plug instead of fixing the mixture in the first place is treating a symptom not the cause.shamrockexpress wrote:B7es for alot of the small block kits seems good for normal conditions.........
