Well after the thrash to Eindhoven/DDD and another 500 odd miles of "Racing my friends" the 1641cc Manx motor is finally dying!
![Cry](http://cal-look.no/lounge/Smileys/default/cry.gif)
on the way home from work today she started to "Knock" and get very HOT
![Undecided](http://cal-look.no/lounge/Smileys/default/undecided.gif)
I know its been getting tied for a while now and I think the last few "Races" have just tipped it over the edge hehehehehehehe
![Wink](http://cal-look.no/lounge/Smileys/default/wink.gif)
It still run's and drives fine but has NO topend power and once warm it knocks really badly under load and is using ALOT of oil, oh yeah and there is a hint of blue smoke drifting from the breather box on idle

its not too much of a problem as winter is nearly upon us and i have been wanting to make a few internal changes for a while ie cam

As a few of you will remember I did alot of work on her a while back (twin carbs, header, etc)

- Lightened and balanced and 8 dowelled 200mm flywheel
- 87mm barrells and pistons
- Stock 311 Con Rods (lightened/balanced)
- CR 9.01:1
- Engle 100 cam
- Straight cut timing gears
- "Bolt up" rocker sharfts with Porsche style swivel feet adjusters
- VW 1.1:1 rockers
- 3/8 thick walled Ali pushrods
- Stock dual port heads 040's with stock valves (mildly ported)
- 32mm oil pump (race trim)

- DDS centre pull linkage (modified with custom swivel piece)

- 30hp fan housing (scat - with oil cooler out the back)

So what are the plans/ideas for the rebuild:- Engle 110 cam/new lifters
- Re-balance of crank, rods, flywheel, clutch, pistons
- slight raise in CR to nearer 10:1
- some more head work especially on the exhaust
- some chamber work, smoothing etc
- 3 angle valve job
- New valve guides
- All new bearings (cam, main, rod)
- New rings (maybe new barrels & pistons but hopefully not)
- oh and a 30mm Berg oil pump (seeing as everyone thinks my mine is too big!)
- and some tips from this handy little thread:
