So, i have been trying to get this Maxi Tuned for a while now, it runs fairly good when cold, but when it gets Hot it just doesn't want to pull at lower Rpm's, Setup right now is:
-No Port Matching on the Block
-45mm Head with 1.3mm Squish
-Completely gutted Stock Airbox
-15mm Bing, 74er Jet
-22mm Stock Exhaust, Short Header
So nothing special about it, but i can't seem to get it right, it runs fine and has no Problem to get up to Speed when Cold, but when it get's Warm it's slower than my stock Supermaxi from a stand still, It runs very well at higher Rpm's and has no Problem going Wide Open, 10'000rpm, for 5km or more…
Now, i tried Different Filters, No Filter at all, Main Jet's from 66-80, 28mm Stock Style Exhausts, Cigar Exhausts, a Techno Boss, testet with Timing from 10-25° and even tested a 12mm Bing bing with a Range of Jets and nothing seems to help, every time, when it get's warm the same thing happens.
