Hello my First post. Never really been much of a fan of face book twitter or forums. BUT THIS PLACE IS AWESOME!! I can’t put my bloody iPad down! Been riding 35 years, was a trackday fan until 2008. Then stopped when we had kids. But recently I’m getting that urge again. So this summer it’s time to dust of my old leathers dig out the tyre warmers and start again. Told the wife and her response was “well why don’t you go back to Jerez this summer” now as much as I’d love to I think I’ll start gently with Pembray My local track. Anyway that’s my first attempt at a post let’s see if it works (us carpenters shouldn’t be given tech).

Welcome in mate, glad to see you have joined in. The 4C8 is an awesome bike and one of the best R1 models in my view, I still enjoy mine.

It'd be great to see some photos of your ride.

Thanks I would but don’t have a clue how to

Two things I’ve learned this weekend
1 I’ve been running my Dunlop’s at the wrong pressure on the road.
2 I need a flash tune! So my 4c8 two stroke can run unrestricted below 7500 rpm!
And it’s all down to you lot on this forum.

Welcome in Dan
Glad your enjoying the forum , you will get out of it what you put in
Your 4c8 looks nice , as for a remap PJC's 4c8 had all the restrictions taken off and was an absolute missile !
Some of the lads do regular track days in the UK and some in Spain , they're always very welcoming to people joining in

Thanks Jompy I’ve read a fair bit of what PJC has to say about the 4c8 anD can’t wait to flash it and see what mr Yamaha had planned before the restrictions were put in place.

Hi Dan & welcome to the forum, pleased you’ve found it useful so far

Thanks Redjj yes there’s no end of useful information on here.

Lovely bike, my favourite colour scheme for the 4C8, maybe I’ll own one one day and find out how they go

Thanks newsh runs ok upgrades in progress suspension sorted Ktech and Ohlins (couldn’t get a Penske on eBay) needs a flash next. Right now it’s flat flat flat then batshit crazy at 9.5k.

welcome buddy,luvly colours the blue white and gold.cracking looking R1 mate.

Thanks Bigun had the choice of any colour when I got it was going to get the black one but changed my mind last minute and I’m glad I did now. I’ve got a black van and it shows every mark!

no mate,you made the right choice by far.looks classy in those colours pal.

Welcome along Dan and glad your finding it useful. Plenty of track nuts here too once you get started and sure you’ll meet a few .

Yes Bigun classy bike shame about the rider!

Thanks Horus looking through old threads looks like I already have!

Christ, wood butcher in the house

Hello mate, welcome in, Damo and myself had pretty well sorted 4C8's, so if you aint sure ask away. For best results, flash, PC3/5, Full Dyno map with a flashtune dealer, sell PC3/5. Bits aint cheap for the 4c8, but if you are scratching the itch again you wont heed much. Or are we going the whole hog with the bike

Thanks PJC been reading loads of your stuff on the 4c8. Got ohlins shock (couldn’t find a Penske on eBay) Ktech rds cartridge kit ,Bazzaz zfitc with self mapping but not fitted quick shifter as I’m running race shift, rear sets,woodcraft engine cases,akrapovic pipes and decat. The Bazzaz has smoothed out the fueling loads (that’s really why I got it) but it’s always been a bit flat low down, had a k5 1000 for a short while awesome low down grunt but it was like riding a mini moto, so went back to a full size bike, I am after all bigger than the average bear. got some other stuff still to fit when I get time -1 front +1 rear and it looks like I NEED a flash tune.

Re-map (flash)

I've got a flashed ecu for the 4c8 for sale mate. It's had the immobiliser removed so can be fitted to another bike. Was off my track bike

Nice bike by the way, love the look of the blue 4C8

I am 6ft 3 and ride a K5

Decent spec bike you are building there

Bazzaz is not a bad unit, not too sure on the map importing though, R1Mike will be able to answer as he is site owner and also Runs velox racing online!!!!

Trust me after a flash alone the bike will be magic, the PC3/5 isnt really needed, it all depends how far you want to go

PJC I’m also 6’3” but on the larger side, got my rear spring from a treactor Messaged velox recently got a quick response was going to call him to discuss further when I’m not”butchering wood”!! Is your k5 fully sorted? Ive still got a load of goodies for one of them stashed somewhere.
