my question is,ive been saving up for a big bore kit on my bike ive read all the threads on here and.and online on for parts.should i do a big bore kit and cams now with 5 speed trans
with cam upgrade kit,no head work on a budget
or upgrade to a 6 speed trans and cams now,with cam upgrade kit
and do the big bore kit in acouple months with splitting the cases and fixing the crank and do a 95-106 kit with ported heads
dont have the money to do it all at once wish i did

Your issue is going to be what cams you are planning on using; cams for stock compression ratio don't always work so well with cams designed for high compression pistons which I presume you plan on using with the big bore kit????

A few cams can work with stock compression and can be pushed close to 10 to 1 compression such as a SE204 and work well for both applications.

If it were my money, I would go for the cam upgrade kit, cams and 6 speed for now. If you are going for a 106, you need a 4 3/8" stroke crank which adds to the cost as you know.

 

i thaught of that too
what cams work with a big bore kit latter on,and a stock 88.prob go with cams for stock 88,add cam upgrade kit and 6 speed for now
latter on when i do big bore kit and get the crank balanced and timken bearing installed. ill get cams for big bore kit prob S&s easy start cams
dont want to use compresion releases
thanks for the advice

 

I did the 95" and SE 6 speed on my '05 RG when it was new. I kept the stock cams as, with the overdrive tranny, I figured that I would be cruising lower RPMs.
The bike has 82,000 miles on it now and it's still the best bike I've ever had, and that includes my '09 EGC.

 

You didn't state which brand transmission you were thinking of, but dc1450 kinda tipped you off if you didn't catch it...

If you are planning on a big bore after the tranny upgrade, make sure to speak with the techs before purchase. Dunno about Ultima or RevTech, but Baker recommends the Overdrive trans for higher horsepower models not the Direct Drive. Phone call never hurts, but may improve your outcome.

 

I don't see any benefit of adding a 6-speed, so spend your money on the motor!

 

 

Not to create a debate over keeping/upgrading to 6sp, but...

I view the 6sp Baker as the single most appreciated upgrade I've done to my '99 RK. Guess you'd have to experience the engine screaming for all it's worth to grab another gear when simply trying to maintain 70-80mph on the super slab before you'd understand the difference. I'm happy with mine.

 

One of the unfortunate consequences of the current quest for low noise emissions (which most of us undo asap) is the greatly increased gearing our bikes (and other vehicles) suffer from. Our bikes are not 'screaming' when they whizz along, as mine does routinely, at around 4,000rpm, that is well within it's and my comfort zone!

When I started riding a long time ago the rule of thumb was that a bike should cruise (and I mean that in the traditional sense) happily at around 3/4 peak engine rpm. So a big twin with a peak rpm of say 5,500 rpm will be happy as Larry at around 4,000rpm. Bingo! With modern manufacturing quality that really is a breeze.

 

I had the same setup and asked about what would work later when I did a big bore, many told me the SE 204's, I put them in and love them, can't wait to see what they will do when I go to my 97 ci bb.
