Is the VN750 a good city bike
I ask the question because my '02 with 8k Miles is on its 2nd battery in 6 months changed under warranty. I'm a daily weekly rider and three or four times since November the bike did not have enough power to start after riding.
Most recently I road for a full day highway and city riding, parked the bike for 2hrs and it would not start had to get a jump. Two weeks before that I took a Lee Parks ARC class and the bike cut off three times during the day's exercises each time I had to get a jump and let the battery charge before it turned over. And Before that day after a week work of daily riding I let the bike sit for two days and it would not turn over without a night on the trickle charge. All of this was with a relatively new battery which was installed in November.
I have K&N filters, use Seafoam ever three tankfuls, regular 87 octane gas, no outrageous accessories , and 80% of the time I ride in the city running errands.
I ask is the bike a good city bike because just recently through the forum It has come to my attention that the regulator rectifier does not charge the battery at idle or at low RPM'S
I have had two separate shops look at and test the components R/R, the stator, and the battery one private shop and the other a dealer, both service checks came back good health charging within spec.
Initially I picked up a cigarette voltage monitor off amazon...it came from China, the digital readout was all over the map which scared me so I found a reported more accurate monitor.
This week I installed up the SparkBright Eclipse Voltage monitor plugged it direct connect to the battery, on my day ride yesterday city and highway riding the voltage indicator reported range 13.20 -14.50v at 4000 rpm or above more highway than city at those rpms.
In the city below a constant 3000rpm 12.45v. At Idle 12.05v.
When the engine is off the indicator reports 12.45v for the battery. Most of the city riding indicating was 12.05v to 12.40v, rpm 2000-3000.
I recently moved the R/R thanks to the forum just in case the issue was the heat.
I haven't hit the 100+ July summer days and I dont want to be worried every time I set out that the bike might not restart after riding.
Question can the mosfet R/R be used in conjunction with the stock stator?
I'm new to the forum, bought the bike last August put 3k miles on it since then , mod the Seat, driving lights with an additional kill switch so no electric drain rarely used, PIAA horn and Ledglow LED lights for night visibility and upsized the tires Commander II.
I enjoy the ride I just need to get a constant charge.
Any and all suggestions welcome.
