Long time reader, first post. Here we go I’m in the space coast Florida elevation is bout 0-5ft todays temps 87 index will prob be hotter humidity will be about 61.
Blaster just got rebuilt by Ken, haven’t even started it yet but here’s my mods. +3 crank 66.5 kor top end Ken’s trail port and polish and head mod shaved to right under race fuel uni two part foam filter in a uni aluminum air box toomey exhaust vforce 4 reeds keihin pwk 28mm(jjh needle 32pilot and 290main) bikes also got banshee suspension all around might be extended I don’t think so but it is lowered and widened in the front and has a banshee rear(needs rear banshee caliper still whoops) then a few atheistic add ons.
#1 Ken just rebuilt my engine but I need to put the clutch cable mount back on …am I okay to loosen the one nut and then retorque it or will I need to loosen all four and retorque evenly around the cylinder.
#2 Hoping i can I get a few techs and/or admins to help with finding harmless jetting start points.
Cuz check it out guy I got it from in north central fl blew the bike up and wasn’t entirely truthful in the sale, this is my second blaster but I’ve worked on a few I knew it had problems but the work done too it was worth the price alone so I bit the bullet. Long story short I know toomey recommends 310 main for the oem mikuni.. a 290 keihin is like a 260/270 mikuni if my maths right(no chart I found went that high so I’m assuming by doubling the conversion for 155 to 132.5) that’s seems pretty low with my mods keep in mind guy thought he was running a 240 he wasnt
. The 32 pilot might be ok for my elevation but I’m not sure on that either I think I’ve seen people running toomey between 32.5 and 35 don’t think they stated elevations. I’m content with the jjh needle for now. I don’t want to blow it up again should I go to at least a 310 keihin to start or should I go higher because of my mods maybe a 340. Also the 290 says AB290 is that a quality jet or should I chuck it in the trash after I order some genuine keihin mains. The pilot is genuine.
#3 I usually run yama R2 mix 32/1 the bikes fresh, y’all anything else or does that sound good I want to keep it cool and lubricated well. I think my last blaster I ran atf type f in bottom end but on my rm250(shoutout to ken he’s building that too) I decided to start using maxima synthetic 100% ester. I read it’s really good stuff it’s real clean for your bottom end, but who knows what’s true when you’re reading stuff on internet… What y’all’s opinion before I try some of either in the blaster, like I said it’s fresh, dry.
I’ve read good stuff about castor and I am gonna get in touch with Ken see if he replaced my clutch plates and if so what he soaked them in.
I won’t be testing the bike for a few days going to rebuild my toomey rear, replace front seal and replace chain sprockets and rollers, and order some new jets.
I need to do heat cycles but obviously want safe jetting to begin with, should I go right into them soon as I know I’m rich or should I make sure I have near fine tune before I cycle also it’s been a few years if someone like AWK or BLAAAASTER or SLYDOG can let me know how they do there heat cycles I’d appreciate it I think you shouldn’t go past 1/4 throttle but it could be 1/2 or 3/4
I will absolutely plug chops Ken recommended I go to a Dyno for tuning I’d love to but I could only find one dyno shop in Florida that has a atv or side by side dyno, and guy is far expensive and he sounded rude.. I’m not that desperate yet. Maybe some of my Florida members know a good dyno shop hidden around here somewhere. Finding a stretch I can reach wide open 6th safely will take some initiative and creativity on my part.
Sorry if this is a lot guys I want this done right so it lasts I’m not the craziest rider and work a lot bike would be getting a few hours a week if that I have already purchased some cheap hrs meters I plan on tieing to the plugs on this and my RM. That way I can be meticulous about engine maintenance. I will be as active as possible on this post even tho it will be a few days until I begin cycles and chops im beyond excited my last blaster was just about stock(and I traded it for the RM
) so I’m expecting a different machine altogether out of this one, hoping it pulls to the moon. But I’m well aware that’s dependent on perfecting this jetting.
Closing with hoping someone somewhere has similar build to me that can get me close or someone with keihin experience around my elevation, temp and humidity can help.
That someone can answer my first question but that I know Ken will, I’ll have to wait till Monday to call the shop tho I won’t bother the man on the weekend open or not.
That I get a bunch of suggestions/opinions for oil types, and that someone drops a real short straightforward heat cycle guide. The Florida dyno I know I’m asking for a lot and I’m not expecting much for that. Thanks anyone for the read and thanksX3000 for any help y’all provide me. Insane reading posts that are 10+ yrs old y’all’s guidance transcends time I appreciate it all. I’ll post pics in the morning
