Project K4 Gixxer

[wackyrider]

Ok, so I'm in need of some technical help as I'm now a bit stumped. The bike is throwing out 14.8V. I have earthed the rectifier with heavy gauge wire going directly to the negative pole on the battery. I have also replaced the rectifier thinking this was the problem, but I am still getting the same issue.

Could it be the alternator is throwing out too much current for even the rectifier to be able to lower enough?? Is this possible? Was mentioned by a friend of Lynton yesterday at the shed while shit loads of head scratching was happening.

Any help would be appreciated as I just want to ride the damn thing now!!!

I heard Lynton doesn't have any friends.

I am not in a position to confirm nor deny such allegations

hey Jules, is 14,8 volts enough to cook the battery?
Had a quick look on the net and found this post. Even tho it is a honda the bloke has a gsxr reg and it is putting out 14,8 volts.
Is there anyone with a k4 1000 you can ask to check their output?

There's a lot of threads about troubleshooting RR, but it's hard to find info on where to buy a good replacement. So here' my story. If you're not into long stories just skip to next message for usefull links.
I bought my 1991 cbr F2 in May 2006 with 16,000. I knew that R/R was a weak spot, so when I had my battery die on me AFTER a ride in October 2006, I decided to check the regulator/rectifier voltage output first. At idle it was about 12.3, and no matter how high I would rev it up it wouldn't read more than 12.4.
Before blaming the R/R I did the stator check: consistent resistance 0.5 -0.6 between each 3 wires and cosistent AC voltage as well
( about 50V at 5000rpm). I also checked resistance between each stator wire and ground- there was no short. That means stator is good.
I also tried to do reg/rect resistence check according to Clymer manual, but you need a special brand multimeter.
I went to www.electrosport.com to buy replacement ( $110). I installed it and around 5000rpm I would get 14.5 V- good!!
I had my headlight off the bike at that time and I did carburator synch( which includes a lot of idling). I finished that and took the bike for a ride- everything seemed ok. Then, before putting the plastics back I decided to check the R/R voltage again to be sure, and--it was 12.3 at 5000rpm. I was shocked!!! My new Electrosport Reg/rec got fried in one day. I did load it up pretty good by idling without headlights for 15-20 mins while doing carb synch but still!!
I took off R/R and did R/R DIODE TEST according to this ( Page C)
http://www.offwidth.co.uk/bike/gener...lt_finding.pdf
I highly recommend this troubleshooting chart.
I found that one of the diodes was bad.
I called electrosport and since my unit has a warranty they agreed to exchange it for me. Later I found out that you can put a suzuki [COLOR=blue !important][COLOR=blue !important]gsxr[/COLOR][/COLOR] unit, so I cancelled my elecrtosport reg/rect and they refunded my money( except for shipping).
I bought a 2003-2004 gsxr R/R off ebay for $20.
It has 5 wires, like honda but the connector is different.
Identifying wires is easy:
Honda Suzuki
3 white( alternator) 3 black
1 Red ( positive)1 black/red
1 green( negative)1 black/white
I cut off both connectors and soldered the wires, since I heard the connectors are a part of the problem anyway( they create a lot of resistence and my cause R/R to burn)
Suziki R/R is much bigger than honda unit, and since I'm kinda a perfectionist I removed all the bolts that attach the plate through which R/R is mounted to the frame. I drilled 2 new holes, so that new [COLOR=blue !important][COLOR=blue !important]suzuki [COLOR=blue !important]gsxr[/COLOR][/COLOR][/COLOR] R/R seats perfectly, I also used CPU heat grease between the plate, R/R and frame( just in case). Suzuki Unit fits perfectly and has enough clearance for plastics and seat. It does seem to give out a lot of charge right off idle and then taper off to 14.5 as rpms increase.( 12.3 at idle 14.8 at 2300 rpm 14.5 at 5000)
I also installed a 5 function digital voltmeter. http://www.casporttouring.com/store/...de=Electronics
I attached it to the speedometer lig

should have done a skid ya pussy. you're getting soft in your old age.

[BANDITROD]

dont do a skid its my driveway you're getting soft Lynton

[stiffsimon]

Hey Lynton

Black's the new black doncha know LOL. Good on yer both Jules' fighter's now ready to fight.

[ozzy1100]

dont do a skid its my driveway you're getting soft Lynton

my driveway my rules... I didnt say I couldnt or havnt done burn outs but as I am the silly fucker left fixing the already fucked thing every one else can get fuck you rednecked hill billy :-)

black is always black ....and this is jules baby, I have just let it live in my shed but I wish he would learn to put fucking tools away before running of to get his dick suxed. I did offer as a good host but apparently thats gay.......

[BANDITROD]

now now jesus its ok lol

my driveway my rules... I didnt say I couldnt or havnt done burn outs but as I am the silly fucker left fixing the already fucked thing every one else can get fuck you rednecked hill billy :-)

[ozzy1100]

now now jesus its ok lol

What happened Rod, you used to be about the cock punch and I thought you loved me lol

[BANDITROD]

hahahaha I will smash youre dickhole with my fist

[Jed]

I think the new challenge for the rest of the year is to do a skid in Lynton's driveway.

Jules. Bike looks great (in the dark anyway). Good stuff. You'll have to bring it to a Test n Tune now

Oops. I thought I put everything away. Sorry for that bud. Hopefully I'll be out of your hair shortly.

Now there's the love ...... Bwahaha

And Jed I knows better than replying to that or I might end up with a name like Frenchy

Name a time and place

Willowbank - Just down the road from Lyntons. Next TNT is Wednesday Night 7th August. I'm aiming to head down. I'll let you know. Gates open 5:30pm

[wackyrider]

Bike now has registration!!! Heall yeah.

Big thanks to Lynton for all his patience and El Hefty for helping out with the roady. You guys are legends.

Now to test ride the bastard and hope it doesn't fall to bits. lol

[stiffsimon]

Good on ya mate, enjoy. Lucky you won't be test riding it here in Melb cause it's pissing down and fuckin cold
