Re: Top-End Reassembly
Today 06:45
A frequently discussed topic...
In my opinion, it always depends on the intended use of the engine/bike: higher valve spring pressures are more justified on a drag bike/race bike than on a pure street bike (especially since the engine of a race bike is disassembled and inspected after the second race anyway), but on a street bike, where a higher mileage without damage is the goal, I wouldn't choose excessively high spring pressures... just my personal opinion and experience. IMHO, most deposits come from worn valve guides, oil seals on shafts, and piston rings/cylinder wear anyway.
But everyone does it the way they want to, according to their own convictions. M-)

I'm after something in-between, and unaware of an other way to achieve it.
Stock just doesn't get it for me anymore, and racing is not in the program either...
