I'm running the ollie cams as well.. but still with standard followers.
If I fins some bonneville followers, I will try that also..
My current engine is now a 84" stroker and breathes through a CV carb.. and has a 16% OD transmission.
I changed both the carb and the cams last winter, so the difference when pulling out the bike of the garage early this year.
With the cv carb and an electronic ignition breaker/point, it always fires up at the first kick when cold. But, with the cv carb you will need to change the timing point for both retarded and advanced..
Easy starting came by advancing the idle timing posisition, and it will actually idle very nice with the cv carb.
The intakes and intake manifold have been massaged with my dremel tool, and the valve guides have been chamfered etc for flow.. and a 3 angle valve seat job, off course.. had to by my own horrible expensive neway 35 degree cutter head.
I have also tried another 84" chief which have ollie cams AND bonne followers. This was much harder to start, but this could also be related to the idle timing settings and stock ignition points.
Out on the road, this bike seems to have a little bit more power in the lower 1/2 of the rpm range. But it falls off sooner than mine, mine just keeps pulling into high rpm. Actually so rev happy that a circlips for the piston pin came off and wrecked the cylinder in july this year.
Now I have new india made cylinders and proper piston pin circlips..and fresh valve seats.. so now it breaths a little bit better.
Also had to redo the valve train at the time..but I still think it's noisy. Probably would need new gears or some kind of coating to quiet it down.
Btw.. there are new intake manifolds coming out of Sweden soon, larger ID (tapered) and ready to accept modern carbs..
And yes.. I have been running a Krankvent for a while. This is a patented free flowing venting valve for the crankcase. It really works great, keeping the oil inside the engine and creates a 100% vacuum (which also should make the oil pump/ splash do it's job)
Well... the idea has reached the dealers.. Geoff at Old Iron should have some in stock.
My own engine got much more rev happy after installing this, instead of acting as an airpump which steals horsepower (ok.. pony power..
I have had lots of problems and have done repairs and improvements over the last 4-5 years (and 50000 kilometers). The last 13000 kilometers(this year) has been the best, now it can be ridden almost like a modern bike..but it still a true indian !!
This winter I will work on project to reduce oil consumption and carbon buildup. The kranvent did reduce oil consumption .. but still a bit of oil goes out the crankcase breather line or ends up as carbon in the combustion chamber(s) .
So, I'm looking into making some kind of mesh (hopefully not a MESS
) inside the camcover for stopping most of the oil spray before it exits the breather line. And then installing valve seals on the intake valves... will se how that works out..
