I was thinking of installing the higher capacity oil pump as seen in the Enfield catalogue No. 7(enfieldmotorcycles.com). Does anyone have any experience in both doing the installation work and in how the pump performs?
Any other performance/maintenance or general improvement mods you can recommend? I'm considering new rockers as well, maybe a one-piece rectifier... and perhaps removing the stock air filter (box and all) and replacing it with a K&N.
Hey Ian, What year is your Bullet? The newer ones (post-99) are reliable enough that I wouldn't think any upgrades would be all that beneficial. I suppose it all depends on what your intentions are with the bike - those catalogues I keep getting from Hitchcock's are so tempting! Realistically, unless you plan on spending as much money on your RE as a Gold Star, it's never gonna be a Gold Star. The stock oil pumps have worked well for 50 years or so under pretty gruesome conditions, but the mod to higher capacity certainly isn't hard to do (about 15 minutes worth of work). The one piece reg/rec might also be of use - cleans up the appearance and is probably a more sound unit to boot. I put a K&N filter on mine and found a noticeable boost at the lower end but it still tops out at about 75 or so - tho' 55 seems to be it's happiest cruising speed. Instead of spending heaps of money on mods that may only take away from the character of the bike, I'd invest in some good service tools and keep the mildly-tuned and seriously reliable little beastie running forever. Of course, that bigbore, stroked 612 kit with dual discs, rearsets, an alloy tank keeps calling my name... Danged ol' catalogues...
Furies and Apaches and Interceptors, oh my!

Yup, all kinds of enticing goodies in those catalogs! I'm trying my best to resist.
My bike has the shorty muffler, a K&N inside the airbox, and it's been jetted richer. I'm not really planning any more engine mods. More power means more heat, and that's a big problem for these bikes.
As for the oil pumps, I've heard the post-99 bikes already have the high-output pumps (I'm not sure if that's true however).

Mine is a 1995, so upgrades may be warranted. It may become a garage sculpture soon, however, before it ever sees a new oil pump.
I wish I HAD a 99! Mine now needs new pushrods, and possibly rockers.
I had to replace the rubber manifolds, the intake manifold housing on the engine, got the clutch adjusted, had to get the carb cleaned and adjusted... but when my mechanic was adjusting the pushrods, he found one was loose and stripped. He recommended an immediate replacement. I rode it home, but it only got about 8 kms before it died.
Now it's back in the shop waiting for the newest parts to arrive. I think I'll name this bike Money Pit... or maybe Black Hole because it sucks everything out of my wallet...
I had expected it would need maintenance and cleaning and some replacements - the rubber bits especially. I wasn't prepared for major engine work.
Maybe when we can get Bullets in Canada again, I'll get a later model...
Hey Ian, After seeing all of the questions you've posted on here I recommend you join the yahoo royal enfield message group http://autos.groups.yahoo.com/group/royalenfield/ (if you already haven't) There are loads of Bullet enthusiasts in that group that will be a huge help to you.
I also own a 95 Bullet, in Canada. So far i have done all of the maintenence needed, myself(replaced stator, rebuilt clutch, decarbonized engine, rebuilt gearbox etc..) Its my first motorbike, so i knew nothing about motorcycle maintenence previous to it. I suggest that you get a manual(Pete Snidal's even) and replace the pushrod yourself(unless you know an enfield specific mechanic?), cause i know that i would almost never trust my Bullet to a UJM run-of-the-mill mechanic.
Enfield Bullet: Symbol of destination.

Thanks. I've joined the Yahoo group, but haven't had time to explore it.
I have the Snidal manual, as well as the workshop book. I just got new pushrods & rocker boxes to replace he existing ones. Hope they cure the bike. Can't afford to put a lot more into it!
My mechanic has worked on Bullets and other vintage Brit bikes in the past (he's the local Triumph dealer too). I have faith in his abilities. I don't have the skills or time or tools right now to do a lot of my own work outside of the basics/cosmetic upgrades, although maybe in the winter I'll have more time.
