20/3 Today I was thinking about the following things:
The guy from Willems Classics was a nice guy. The only thing I didn't like was the way he was trying to sell engineparts. If I follow his advice I would probably end up with 140 BHP at 9000rpm engine. He is trying to sell all the bronze parts like the cam followers, the valve springs. If I take an other crankshaft the needles in my carbs must be changed. It could be a never ending story.
An other thing which worries me is the gearbox. Thinking about the way he/they did the engine.. What would be the state of the gearbox. I haven't had real problems with the gearbox. Only between 2nd and 3rd gear....a little bit of 'teethbrushing' that's all..
I'll think about it.
21/3 My girlfriend told me that the purpose of me building this site is purely psychological. I'm cooping with the harsh reality or something. hehe
Anyhow, during work I was thinking about all the other things that can be changed. (Why not?? There is a moneytree in my backyard...) That thought is probably very psychological. I don't trust anything in my car right now. So when I change it myself I know what happend with the car. Funny!! I'm having some sort of deja vue. My father always told me that he doesn't buy secondhand cars because....... Right, you don't know what happenend with it. He is right in a certain way. On the other side, old cars are nicer and more elegant, more mechanical, less aerodynamic. Try to find an old car which isn't secondhand.
Back to the subject. Airfilters. I've got these functional airfilters without the filterbox. I removed the original thin filters and replaced them with these cardboard-like filter. I like the K&N or the pipercross filters. Very expensive but HIGH PERFORMANCE. When you buy one of these you should also buy a rampipe. It has got something to do with the airflow (a friend of mine explained me the problem.) Without the rampipes the airinlet could react as a smaller inlet because of the angle the air has to travel. In a nutshell, more horsepower with better airinlet.
I sounds terribly nice but is it worth the money. They say K&N airfilters last for ever and are cleanable. Pipercross is quit expensive and I believe you have to modify them to fit your HS2 carbs.
Hmmm this brings me to the idea of changing my carbs. into webers??
27/3 Back again.. The webers right.. It will cost me a lot of money and I really don't know if the weber are going to make the big difference. An other option would be replacing the SU HS2 into SU HS4. I don't know how much a HS2 could produce but the other week I heared a HS4 alone could manage around 75 BHP. What would I want with 140 BHP. Well to be honest I think the HS2 could handle enough BHP when they are carefully tuned. Let's see what happens within two weeks when they tell about the damage in the engine. 3 weeks is a long time to wait. During this waiting I keep wondering if I made the right decision. Is it worth the investment. I could rebuild the engine with a friend of mine. It would probably save me a lot of money. But still I have to contract out the drilling and the honing. And there are some other precarious moments during the engine build up. If you don't do those things at the correct way you could also end up with the damage I got...
When the engine is finished and you have to start the engine for the first time it's important you keep it above a specific RPM. It has got something to do with the pistons and the cylinder.
