I am selling the front and rear end of my bike. They are listed on ebay in the UK front end rear end

I am new too to the forum but may help I think. You may want a boyer bransden or pamco system. Other may probably correct me if I am wrong.

Yep thanks, emailed the Dutch chap and he came back with a cam spec that would suite.

Wow Jack, thanks a million, well explained especially on the intake side. I was going to go with 36/38 mikunis but I may stick with what I have 34 AMAL and see how they perform.

More questions: Where can I get a 270/90 crank spline ( I think someone in Oz does one), not sure which way to go with the re-phase, 270 or 277? Where can I get a "hot/race" cam for the above. How do you remove the pins in the dog gear selector. I managed to removes the safety clips but the...

Great looking project. Keep us updated

Here are some more pics, There is some silicone in the usual place (was told it is a Halco mod due t0 the area being prone to be too cool). The carbs I have are AMAL 34mm anyone know if they are any good? Internals llok good except some wear on the clutch basket. Will get it all cleaned up...

Yeah thanks ( I eventually did a search and found a thread , sorry the punt). Bastard bolt/phillips heads were all chewed up. Engine internals looking good, suzuki pistons and cylinder bore hardly scored. Clutch is also an 8 version.

SO far I have managed to unbolt every nut and bolt on the outside of the case but I am strougling to split the case and I don't want to damage it, am I missing something here?

Here are some pics of the engine taken with my phone

By the way the bike came with AMAL carbs, anyone got any ideas on their performance? this was my previous project

Yep i think I am going to do the 277 change. I found a engineering company in nottingham who has experience doing it and charge £80 for the help, they can also cut and reweld the cam to suite. I think the first job is to strip and bag the parts then send the engine to get cleaned, bead blasted...

I need to take the valve out will do this weekend (including full strip down of the rest of the engine). I am still toying with a rephase but really don't want to spend too much. I am still trying to learn the easiest method i.e. without the need of an additional crank.

Good news, It is a 840 Halco ( I am actually surprised), took the head of ( I going to do a full rebuild) and measured the diameter to 85mm and it had a Halco gasket. The head valves were slightly rusty. I am going to go the whole way and split the case and get everything properly clean...

Hiya, Thanks for the quick reply, I managed to get the engine out of the frame in 40 minutes, love old tech, especially when the engine is so light.. The previous owner/s have looked after the bike as it has a lot of one off stainless parts, e.g. mounts, bolts etc. I'll split the engine over...
