    Should I do this?

    Dyna Ignition

    EV27 Cam

    Andrews Adjustable push rod kit

    Mikuni HS42 carby Or should I keep the standard CV carby and just re jet it to suit my needs?

    Torrington cam bearing

    Hi flow air filter

    Ive travelled 70,000KLM to the day. It gets ridden every day(all most anyway), at the moment It has never failed me but it is stock standed other than the pipes & Hi flow kit.

    I want to acheive more bottom end power but still have super reliabllity on long trips?

    thoughts anyone in the know?

    If its given you 70,000 k`s trouble free, leave it, in my opinion i would not try to hot up a 70,000 k motor, it will put stress on an already worn motor and you will soon have a failure.

    Rebuild the bottom end and the top end then go for an increase in compression and have someone (that is someone who knows) specify ign,cam,pipes then look at the g box, clutch belt,  if you hot up the motor alone some of the driveline will be prone to fail.

    What you said is what I'm thinking too. Better to wait and do it properly aye.

    Actually Scap that, I dont think that for the amount of extra horse power the mods will make to the motor it will stress anything out too much!!

    mates with great respect I would not consider a motor with 70k to be anywhere near worn. Hell thats only about 50-55 k MILES or so... (don't have my calc with me to do the conversion).

    I pulled my cylinders off the softail at 65,000k to do some performance work and the cross hatchings on the cylinder walls was still in great nick.

    At this time I did this build specifically for longevity with Scott from Hillside Cycles in Munnsville New York who did the heads (beautiful headwork) to 9.7/1 comp, took out the EV27 and threw in a Woods W6, added Andrews beehive springs and a DTT igniton (to replace the SE single fire ignition-- already had a S&S E on it) and it runs very well. I don't flog it but when I get on it the power's there as needed.

    Daniel if your just going to throw a cam in it, leave the CV on-- it's good for 85hp and although the throttle response will be slightly slower than with a Mik or S&S don't worry about it-- you don't really need anything 'bigger' than the CV.

    I suggest your proposed list won't hurt a thing on the motor unless you flog the shit out if it past the redline constantly.

    Just my take and others may differ but it works for me.

    I must stop comparing all harleys to shovels, good points from people with actual experience, with all that reliability what do you guys do over winter

    I've put EV27 & ignition in two mates bikes recently, both used the rejetted CV carb, they have over 80000kms, they now go much better than stock & the owners both said they should have done it years ago.

    I also fit new Lifters & cam bearings for peace of mind.

    If you remove rocker covers etc. you can use original pushrods.

    hi, you don't say  what model bike  & year ,  pre 91 -92 have the stronger torrinton inner cam bearing  stock ,  but if you are looking for a bit more  & it's about time for a top-end  job anyway  new rings & a head service , a new cam & inner bearing & new cam followers  at least.             crane 310-2 work's well in a heavy bike like s/tail or dyna  take -0.020"  of the heads & 0.008" - 0.010" of the bottom of the barrel as this will help with squish & barrel gasket surface sealing ,     if your not a flogger  the stock carb modified is good .       cheers

    Well due to christmas and the new arrival of Mya I have only ordered the bare minimum for the minute.

    EV27 Cam

    Torrington bearing

    Andrews adjustable push rods

    this should do for the time being.
