HT-b cam - improved version
- Thread starter sam2019
- Start date
Hey Old Man (that doesn't sound right!?)
Your observations are spot on. I've quite using my b Cam for this reason, but I'm hopeful that a Newer Version of this Cam, with the inclusion of a Decompressor, will be available before too long. I too liked the extra torque that was produced so I'm anxiously waiting for this new rendition.

For some reason, this morning I had to roll back to help the starter
yesterday was okay.I have found that holding a small amount of throttle and hitting the Button works most times, rolling back has reduced since adopting this technique.
What other Mods apart from Cam shaft?

Well, I do always pull the clutch and still have the occasional near-TDC effect where the piston gets stuck and I have to press the button a few more times before it rolls. Thats on a 411 with only the cam and measured 180 psi compression.
I'd say that it's just a poor quality battery, without sufficient CCA to crank the starter...
My lithium battery has never failed to spin my 477 with cam and 210psi...
you could be right, these indian lead acid batteries are shit, I have a collection of 5 or so bc permanent failure. @Dool you have a Lithium but you also have sometimes this starter problem, right?
My starting problems have only come up in less than a Year I dont remember it being an issue until overdid the Compression a few times and Overloaded the poor not so well made starter motor. But it just occurred to me that we have well sealed engines or weak starter motors
The Voltage shown on my Bikes is always 13 plus, it is amazing how much Punch these little lithiums have, I remember when I fitted the first and bigger of the 2 and it was noticeably faster than the near new Mottobat which was perfect
just heavier!

Mine tho is just a 411cc with 36 000kms on. Might be the Motobat battery that I have too, though I did go through the starter wiring when my Indian battery started playing up after 3 years. Cleaned all the wire terminals, starter posts and starter relay terminals and then sprayed them with silicon spray after reassembly to stop corrosion.
That was not the question. Do you sometimes have starter problems in spite of having a Lithium - YES or NO?The Voltage shown on my Bikes is always 13 plus, it is amazing how much Punch these little lithiums have, I remember when I fitted the first and bigger of the 2 and it was noticeably faster than the near new Mottobat which was perfect
and perhaps will be again.
I’m not sure if this is purely a coincidence or if there’s something else going on. I recently bypassed my clutch switch and since then I haven’t had any issues with the starter not being able to turn the motor over. What I have noticed while looking at the wiring diagram is that when the clutch lever is pulled in the switch pulls directly from ground and when the lever isn’t pulled in the low signal (ground) comes from the ECU. I have the switch bypassed directly to the ground wire. Has anyone else bypassed their clutch switch to ground and isn’t having the frequent starter issue? I know it seems odd but I I was frequently having issues with the starter not turning over the motor and now it’s seemed to have disappeared. Could it be the starter solenoid isn’t fully engaging when having to go through the ECU?
No. I had already bypassed my switch before others had suggested pulling it in while starting. I’m not pulling it in now since I don’t want to change what I’ve been doing to see if the bypass truly made a difference.

Yes but if the switch is out of the way then surely it wouldn't matter if the clutch is pulled.
Main thing is you have it starting well, surprisingly my latest build at 240psi has not had any problem with starting and no Decompressor.

That is an interesting take and it matches my observations.
I recently took apart the clutch switch because it wasn't functioning properly and I found out it's just a 0,02 cent piece of rubbish. Metal lines inside the switch tend to oxidize while you looking at them and if there is corrosion on the switch, a good deal of power (due to added contact resistance) will be lost before reaching the starter motor.
I think bypassing the clutch switch altogether is the best way to go, I'm adding this to my "to do list" on the bike when it goes in full overhaul mode.
I might even bypass the side stand switch and get rid of the side stand altogether, my bike is now too tall anyway to use it (leans too much on the side) and I can save a kilogram along the way...
I like the idea of a switch that stops it being started in gear as I like a switch to stop me riding off with the side stand down.
But if the switches are crap then the Idea is also.
I bought a aluminum cover for the side stand switch( too much time on my hands!) went to fit it and it was not there! the switch that is

For those interested in bypassing the clutch switch the two outer wires on the switch connector need to be jumpered. I just cut the connector off and soldered them together. The center wire goes to the ECU and the end should be protected from shorting out.
