BW, The cams are the best thing for making the bike go like a bullet.I also. noticed that after putting back the BS32 carb on my bike the low rpm torque seems much improved as compared with the TM flatslide. The bike actually does power wheelie in the first if I pop the clutch. However the bike's top end has dropped with this carb. Do CV carbs help boost low end torque? Secondly, once the rpms cross 4000 the clutch starts to slip despite having stronger Endurance clutch springs installed !! Is there way to improve the AVL clutch with use of better springs or different clutch plates? I did run the bike without the oil in the primary side as a test and that stops the slip. But I don't think that is a solution. Any suggestions from AVL members with S cams will be helpful. Thanks.
Thank You for the reply Bill. Appreciate the tip on the ATF F type. I will work on the bike this weekend and clean up the clutch side before replacing the oil with ATF. Will update once I get to it.Did you have any cam-follower wearing out issues with you bike (using the AVL cam followers) ? The exhaust follower wore out so I had replaced both recently, however, it seems like the followers are again starting to wear out again. Thanks,Tej
Hi Ace, Bill, You maybe be right on with the oil - with the old cast iron engine getting phased out its getting harder to get engine oil specifically for the 'Bullet' so I have been using 20W50 which is meant for petrol car engines. Will adding an oil additive like STP help. I will definitely use a high Zinc /PH oil after I manage to replace the followers with new ones. Thank You.
BW,What octane do you use in your 500 9.2:1 compression AVL engines?Cheers,Bill
Finally, finally got around to installing the cams. Couple of hiccups: 1. For the life of me, cant find the timing marks on the pinion!! Had to mark it myself based on TDC and original cam locations.
TejK,If your clutch is adjusted correctly, try F type ATF in your primary. I use this in the Harris Scrambler and get no clutch slippage at all, pulling hard at any RPM. This on the stock clutch with over 35,000 miles on it.Royal Enfield people are good peopleCheers,Bill
........The clutch has definetly improved with the clutch engaging quite positively now. Haven't found any slip after using the ATF. I couldn't find the F type and am using the A type ATF which was available.........
